Whether you enjoy brainteasers or a good old-fashioned jigsaw puzzle, this day is for you. Take a few minutes (or hours) today to complete a puzzle of any kind. If you like numbers, try Sudoku or Kakuro; if words are more your thing, take a stab at a jumble or wordsearch. Not enough of a challenge? You could always make your own crossword puzzle!

No matter how you choose to celebrate, try to share the joy of National Puzzle Day. You could give away a few Rubik’s Cubes to friends, or donate some great jigsaw puzzles to a children’s home or hospital.
